given how it dismissed that model, it seems odd that this article then immediately starts talking about the ‘electron gas’ and throws around an analogy of voltage to a pressure difference in the gas. Apparently the pneumatic model is preferred over the hydraulic one. Personally I think the problem with the ‘hydraulic model’ is that people visualize it with wires as fluid filling pipes, with pressure as the driving force. I think you get a lot further if you imagine your circuits as water running in open channels with a free surface. The water needs to be able to slosh.
